Applying the H/V Method to Dense Cities. A Case Study of Valencia City

The aim of this study was to apply Nakamura's technique to Valencia city center, after some preliminary tests in Barcelona. Previous studies of Barcelona had measured periods in restrictive conditions and in various types of material ranging from very soft soil (with a predominant period of approximately 2 s) to rock (0.3 s), and under different measurement conditions. The Valencia city center measurements were taken by using the distance from buildings and car and pedestrian traffic to construct a measurement grid that was as regular as possible. We also estimated possible soil-structure interaction to detect potential vulnerability.     

Le Conte de deux cités1 : Analyse comparative des conflits urbains de Montréal et Valence, 1995–2010

A tale of two cities: 9 Comparative analysis of urban conflicts of Montreal and Valencia, 1995–2010 Metropolization processes at work in contemporary societies produce social and spatial change, which can raise strong opposition from a variety of urban actors, leading to acts of dissent. While such urban conflict has been examined in the past, geographical analysis of urban conflicts as sociospatial processes is more recent. Systematic quantitative research on urban conflict is virtually nonexistent in terms of comparative analysis conducted with an international perspective. Systematic comparative analysis sheds light on the existing relationship between urban conflicts and the socio‐territorial contexts in which conflicts emerge and evolve. This article presents a comparative analysis of urban conflict that occurred in a selection of boroughs in two cities characterized by different geographical realities, Valencia (Spain) and Montreal (Canada), between 1995 and 2010. Spatial autocorrelation techniques applied to a conflict database show a significant relationship between the emergence of urban conflict and the spatial distribution of some contextual variables. Indeed, for Montreal as for Valencia, the concentration of urban conflict is the greatest in the most deprived neighbourhoods. Also, regarding the management and regulation of urban conflict, results shed light on important differences between Montreal and Valencia. These differences include the outcome of urban conflicts, repertoire of action of actors involved in conflict activity, and the type of contestation faced by actors who promote the challenged urban projects.     

Archaeological microgravimetric prospection inside don church (Valencia, Spain)

The microgravimetric surveying technique is applicable to the detection of shallow subsurface structures if a lateral density contrast is presented, and thus, it is a valid technique for archaeological prospection. In this paper, this technique has been revealed to be an efficient tool for archaeological studies, such as those performed inside Don Church (18th century), located in the urban area of Alfafar town, Valencia (Spain), where a buried crypt, suggested by different boreholes drilled during the second restoration process in 1993, is expected. Details of the site’s characteristics, topographic survey procedures, microgravimetric field operations, data collection and gravity reduction operations (where the inner building effect of walls, pillars and the altar is confirmed as one of the most important) are also presented. Finally, the results confirm the buried crypt.     

Food in the accounts of a travelling lady: Maria de Luna,queen of Aragon,in 1403

ABSTRACT

A household account book of Maria de Luna, queen of Aragon, dated 1403, serves as a guide to her everyday life and especially her diet. Its contents give us details that normally go unnoticed, about the court, the quantities and qualities of their foods, the means of preparing them, and the spectacle of the queen and her courtiers at table. The peripatetic nature of the queen’s household brought her to different towns in the interior of the kingdom of Valencia, and the document provides important – and rare – evidence of the impact of the court on these small markets, and the strategies for providing foods of the highest quality to meet the demands of the queen. The household is compared with others of similar rank in the Iberian Peninsula and nearby.     

Diagenesis of the Amposta offshore oil reservoir (Amposta Marino C2 well,Lower Cretaceous,Valencia Trough,Spain)

Samples from the Amposta Marino C2 well (Amposta oil field) have been investigated in order to understand the origin of fractures and porosity and to reconstruct the fluid flow history of the basin prior, during and after oil migration. Three main types of fracture systems and four types of calcite cements have been identified. Fracture types A and B are totally filled by calcite cement 1 (CC1) and 2 (CC2), respectively; fracture type A corresponds to pre‐Alpine structures, while type B is attributed to fractures developed during the Alpine compression (late Eocene‐early Oligocene). The oxygen, carbon and strontium isotope compositions of CC2 are close to those of the host‐rock, suggesting a high degree of fluid‐rock interaction, and therefore a relatively closed palaeohydrogeological system. Fracture type C, developed during the Neogene extension and enlarged by subaerial exposure, tend to be filled with reddish (CS3r) and greenish (CS3g) microspar calcite sediment and blocky calcite cement type 4 (CC4), and postdated by kaolinite, pyrite, barite and oil. The CS3 generation records lower oxygen and carbon isotopic compositions and higher ⁸⁷Sr/⁸⁶Sr ratios than the host‐limestones. These CS3 karstic infillings recrystallized early within evolved‐meteoric waters having very little interaction with the host‐rock. Blocky calcite cement type 4 (CC4 generation) has the lowest oxygen isotope ratio and the most radiogenic ⁸⁷Sr/⁸⁶Sr values, indicating low fluid‐rock interaction. The increasingly open palaeohydrogeological system was dominated by migration of hot brines with elevated oxygen isotope ratios into the buried karstic system. The main oil emplacement in the Amposta reservoir occurred after the CC4 event, closely related to the Neogene extensional fractures. Corrosion of CC4 (blocky calcite cement type 4) occurred prior to (or during) petroleum charge, possibly related to kaolinite precipitation from relatively acidic fluids. Barite and pyrite precipitation occurred after this corrosion. The sulphur source associated with the late precipitation of pyrite was likely related to isotopically light sulphur expelled, e.g. as sulphide, from the petroleum source rock (Ascla Fm).

Bound by blood: the ethnic and civic nature of collective identities in the Basque Country,Catalonia and Valencia

This paper explores the factors determining collective identities in the Basque Country and Catalonia, paying special attention to language and birth as key domains of ethnolinguistic divide. We will also make a comparison to the case of Valencia, a region with a native language that nevertheless has not developed a nationalist movement. We have performed a cluster analysis to compare the differences between collective identities in these regions using data from the survey on National Identity in Spain, and discriminant analysis is used to test the validity of our model. Results show that an ethnolinguistic division, based on parental origin and linguistic skills, defines peripheral identities in the Basque Country and Catalonia, but this singularity cannot be found for Valencia. Finally, our model corroborates the relevance of ethnolinguistic factors in defining collective identities in the Basque and Catalan regions, while the civic factor may be more relevant in Valencia.     

Arnau de Vilanova at the summit of Oloron (1287): a major inflection point in the life of a medieval physician

In July 1287, during mediation by Edward I for the release of Charles, prince of Salerno, the kings of England and Aragon met with Charles' representatives at a large assembly at Oloron in Béarn, on the edge of the Pyrenees west of Bayonne. An English document deriving from this meeting reveals the presence there of the famous physician Arnau de Vilanova, a member of the Aragonese party, and recipient of a gift from the king of England. This article demonstrates how this document and other recent discoveries, properly contextualised, can illuminate an obscure period in Arnau's life in which he turned towards a new pattern of existence.     

‘Unfortunate Jews’ and urban ugliness: crafting a narrative of the 1391 assault on the jueria of Valencia

On 9 July 1391, a mob assaulted the Jewish quarter of Valencia, killing and forcibly converting its inhabitants. This attack, one of many across Spain that summer, is much debated as a turning point in medieval Jewish history, but little attention has been paid to the role of the urban government. This article shows how the city council of Valencia shaped its narrative of the assault to further its goals for urban reform. In 1391, the Valencian council was in the midst of a reform initiative informed by the principles of Christian urban planning in Francesc Eiximenis’ Regiment de la cosa pública. The jueria was seen as an impediment to reform. The council’s retelling of the 1391 attack shifted responsibility onto the Jews and the jueria itself, considered a block to public order in the city. This laid the groundwork for the council’s solution: the removal of the jueria from Valencia.
